Looks like a labor of love and now you have something that is going to get a lot of attention when your out and about. Thanks for posting those photos. Nice job!

Looks to me you did an outstanding job, can't see any flaws. What quanity of dye did you order? Is it safe to assume that there will be zero transfer of stain on your clothes when you sit on them. I think I can come up with a few things that I might have to do that too.
I have no idea on where to get a new top, as mine is in fantastic shape. But since you seem to own one, do you know where to purchase a windshield? I tried a couple glass shops for my 1991 conv and came up with zip.
I pulled my stock two core radiator and had it remade into 3 core still staying the almost same dimensions to fit within the alotted space. The shop took the measurments and figured what they could buy for a core, reused my side tanks. It did help in lowering the engine temps some. The radiator shop was local to me and seemed knowledable about doing what I needed. Don't recall what I paid but it seemed like a decent cost. I have a 91 conv.
